Richard Shelby, 27, was picked up during a routine traffic stop, Johnson City Police said. He didn't have any identification on him, but police eventually found out he was wanted in Lafourche Parish on charges of first-degree murder and crack cocaine distribution.

Shelby lived in Raceland when Derrick Boveland, 30, was shot, and was living in Johnson City when he was arrested, police said.

The Lafourche District Attorney's Office dropped first-degree murder charges last year against Amos Washington, the man Lafourche sheriff's detectives accused of pulling the trigger, because of a lack of evidence in the case, Lafourche District Attorney Cam Morvant II said.

Nathaniel Bradley, who detectives allege was driving the car while Washington shot out of it, pleaded guilty a year ago to negligent homicide and was sentenced to five years in prison.

Before these two cases were resolved, all three men fled to different states at some point, authorities said. Washington was caught in Mableton, Ga., in May 2010, and Bradley was caught in Texas three months later. Shelby remained the only one at large.

Washington fled right after the shooting, but deputies jailed Bradley and Shelby. However, a grand jury decided in 2008 that there was not enough evidence to indict the two men, and they were freed.

A second grand jury indicted all three men on first-degree murder charges a month after Washington was caught.

On Monday, District Attorney Cam Morvant II said he will request that Shelby be extradited to Lafourche Parish.

The outcome of Shelby's case will not allow prosecutors to bring additional charges against Washington or Bradley.

According to detectives' accounts, an incident involving Shelby led to Boveland's July 14, 2008, shooting. Detectives first talked to Shelby at Thibodaux Regional Medical Center, while he was being treated for a gunshot wound. At the time, Boveland was in the same hospital in critical condition after being shot in front of his Marydale trailer.

Richard Shelby told detectives that while he was out at the club Beady's in Thibodaux, now Rak-A-Dak, members of the Marydale-based Baby Click gang were harassing him and wanted to fight with him, according to the detectives' report.

"So he left, embarrassed," the report says.

Shelby said he called his cousin Washington, and Washington and Bradley picked him up. Then, they drove around "looking for the guys who wanted to fight with him," detectives said.

The three mistook Boveland for a Baby Click member, Marydale residents said at the time. Baby Click allegedly had an ongoing feud with a group known as the 600 Block from Raceland's Alidore community.
